DABBING-BRUSH-ACIUATING MECHANISM FOR WOOL-COMBING MACHINES.

SPECIFICATION forming part of Letters Patent No. 462,598, dated November 3, 1891.

Application filed April 13,1891. Serial No. 388,702. (No model.)

To to whom it may concern.-

Be it known that I, JOHN SOOTHILL,a subject of the Queen of Great Britain, at present residing in Johnston, in the county of Providence and State of Rhode Island, have invented certain new and usefulImprovementsin Dabbing- Brush-Actuatin g Mechanism for \Vool-Oombing Machines; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to improvements in that part of a wool-combing machine known as the dabber-driving pulley.

The object of this invention. is to produce a new and improved form of dabber-driving pulley which will continue in its operation for a short time after the comb has ceased to revolve. To attain this end I have invented certain novel features of construction and combination of parts, as will be more fully described hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of a counter-shaft support of a woolcombing machine and the dabber-driviug mechanism secured thereto. Fig. 2 is a vertical sectional view of the improved dabber driving pulley. Fig. 3 is a View of the inner construction of the improved pulley.

In the ordinary construction of a woolcombing machine the dabber-driving pulley is rigidly secured to the counter-shaft and stops and starts with the mechanism driving the comb and other portions of the woolcombing machine. In consequence of this construction the wool lying between the comb and the dabbenbrush remains in that position until the machine is started. As the comb begins to revolve at the first motion of the driving mechanism, the wool which has remained between the comb and dabber-brush is apt to be carried pastthe brush before the brush is driven against the wool sufficiently to force that portion of the wool into the comb, thus causing what is called a fault. My invention is for the purpose of overcoming such faults, and I Will now proceed to describe it more particularly.

-At the outer end of the counter-shaft 5 is secured the balance-pulley 8, which is revoluble thereon, and has an inwardly-extending circumferential flange 9, the inner edge of this flange 9 moving around in easy contact with the back plate 10, which is secured on the counter-shaft 5 by a set-screw 11 and is provided with the spindles 12 12, to which are pivotally secured the spring-operated pawls 13. These pawls may be operated, as shown in the drawings, by coiled springs 14, carried on rods bearing against the ears 15; or they may be operated by other suitable springs, the ob ject being to force the end of the pawl into contact with the teeth of a ratchet-wheel 16, carried on'the sleeve 8 of the balance-pulley 8 and secured thereto by a key 81. The teeth out on the ratchet-wheel 16 are cut in a direction so that b I contact with the pawls 13 they keep the balance-pulley 8 on the flange 9, on which the dabber-driving belt 17 is carried, from turning backward. The dabber-brush is carried on the rod 18, which is moved up and down by a block sliding in guides in the frame 19 and operated by the crank-eccentric 20 and pulleys 21, to which motion is imparted through the belt- 17.

The operation of my improved pulley is as follows: \Vhen the belt 7 is shipped from the tight pulley (J to the loose pulley (3, the belt driving the comb will also be shipped and the comb stopped. The weight and momentum acquired by the balance-pulley S will, however, continue to revolve that pulley independently of the counter-shaft and to drive the dabber mechanism through means of the belt 17. The dabber-brush will thus be driven down against the comb several times and sufficiently to force the wool lying under the dabber-brush into the comb. \Vhen now the machinery is start-ed, the pawls 13 will engage with the ratchet-wheel l6 and drive that wheel and the balance-pulley 8, carrying the belt 17.

The dabber-brush will begin to operate before a new supply of wool is presented to its force, and therefore no W001 can, pass away from under the brush Without being thoroughly combed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a Wool-combing machine, a balanced dabber-driving pulley independently revolving on the counter-shaft and provided with a ratchet-Wheel, and mechanism carried on said counter-shaft and adapted to engage said ratchet-Wheel to drive said pulley, as described.

2. In a wool-combing machine, the combination, with the dabber mechanism and a belt adapted to drive such mechanism, of a bal- Witnesses:
